Study of Mortars Made with Natural and Artificial Pozzolans [PDF]
The objective of this work is to evaluate the thermal activation potential of clay soils, particularly the clay fraction of dam mud, for the production of artificial pozzolan which can be substituted to cement in concrete and mortars applications and ...

The comparative study of some effects of natural and artificial pozzolans on the hydraulic properties of Portland cement mortar is performed in this work. The natural pozzolan used coming from the Djoungo deposit, Moungo department in the Littoral region (Cameroon) was finely ground and then sieved at 100 μm.

Properties of Artificial Lightweight Aggregates from Various Pozzolan Materials – A Review [PDF]
The use of lightweight aggregate can bring advantages to the construction field. Lightweight aggregate has been used due to its lower density and can reduce the dead load applied to the structural elements. Due to the number of natural resources, such as

An ANN to Predict Sorptivity and Water Absorption of Concrete Made with Industrial Waste and Artificial Sand [PDF]
Large-scale cement and natural fine aggregate use in construction has negative environmental effects. In light of this issue, crushed sand is a good material, and wastes from industries such as metakaolin, Furness ash, blast furnace slag, and micro ...

Evaluation of Pozzolanic Reactivity of Artificial Pozzolans [PDF]
Pozzolanicity is a very interesting issue regarding building materials, as a way to enhance mortars and concrete durability. This property results from the reaction between calcium hydroxide and silica and alumina based materials. Different types of natural and artificial pozzolans show pozzolanic activities that differ depending on the materials ...

Concretes with binary mixtures of artificial pozzolans and concrete demolition waste [PDF]
Abstract The objective of this study is to analyse the use of binary mixtures of pozzolanic materials and concrete demolition waste in concrete mixtures, especially the resulting mechanical properties and durability. A total of ten concrete formulations were produced distinguishing them in different types using different Portland cements, different ...
